defined as HALF OF THE DISTANCE between the NUCLEI of neighboring atoms in the pure element
ATOMIC RADII (size)
atomic radii is expressed in ___
ANGSTROMS
the ENERGY REQUIRED to REMOVE AN ELECTRON from a gas-phase atom
IONIZATION ENERGY (IE)
the ENERGY CHANGE that occurs when an ELECTRON IS ATTACHED to an atom in the gas phase to form a negative ion
ELECTRON AFIINITY (EA)
MEASURE OF THE RELATIVE TENDENCY of an atom to ATTRACT ELECTRONS TO ITSELF when it is chemically combined with another atom
ELECTRONEGATIVITY (EN)
these are not included in trends
NOBLE GASES
TREND OF ATOMIC RADIUS
the closer to the lower left side, the bigger the size
TREND OF IONIZATION ENERGY, EA, EN
the closer to the upper right side, the higher
most electronegative element
FLOURINE
